consul.yml consul-haproxy infrastructure doesn't seem to work with consul-template 0.18.1

[mariusneo]

I've made some experiments locally based on this demo project (branch master) and while trying to do some experiments I've noticed that not the latest consul-template is being used

I had a look on
https://github.com/camptocamp/docker-haproxy-consul/blob/master/Dockerfile

and seen that the latest version of consul template is used

ENV CONSUL_TEMPLATE_VERSION=0.18.1

Can it be that the latest version of camptocamp/haproxy-consul:latest is not quite up-to-date?

I've build the docker-haproxy-consul locally and referenced it in consul.yml file and got the following error while executing docker-compose -f consul.yml up

Any ideas why this happens?
